Definitions

  • This invention relates to an improvement in rotary speed regulating devices for output shafts of cloth-pulling rollers in puller apparatus provided to pull cloth toward its feeding direction in co-operation with cloth-feeding mechanism of industrial sewing machines etc. (When this puller apparatus is provided at the feeding side of cloth, it is utilized as a so-called feeder device for cloth.)
  • Rotary speed of said output shafts must be properly increased or decreased corresponding to the cloth material, but in customary speed regulating devices, rotary speed of the output shafts has been varied by transferring the pivot part at one end of an eccentric rod, pivoted movably in a diametric direction of the input shaft, to a desirable radial distance, and fixing at that position; hence in the case of said regulation, such operation as loosening and retightening of fixing bolts etc. of the pivot part at one end of said rod must be performed. Accordingly this regulating operation has been a troublesome matter and inefficient operation, since the transmitting mechanism such as the eccentric rod is received ordinarily within a main body case.
  • a rotatable adjustment member carries a worm meshed with a shaft-mounted worm wheel, and a linkage connects the worm wheel shaft, the end of an eccentric rod, and the operating member of a unidirectional clutch, such that the rotary speed of output shafts carrying the cloth-pulling rollers can be regulated precisely during operation merely by turning the adjustment member.
  • FIG. 1 is a front elevational view, partially in section, of a puller device in accordance with a preferred embodiment of this invention.
  • FIGS. 2 and 3 are schematic drawings illustrating operation of the device of FIG. 1.
  • 1 is the main body case of puller apparatus
  • 2 is an input shaft bearing-supported properly on said case, and is located outside the case.
  • follower gear 3 is secured to one end of said input shaft, and it is constituted so that input shaft 2 is rotated in co-operation with cloth-feeding mechanism of a sewing machine (not shown) when power at the sewing machine side is transmitted to said gear through a timing belt etc.
  • reference 4 designates flange secured to another end of input shaft 2 located within the case, and one end of eccentric rod 5 is pivoted on this flange by pin 6, and one end of each of links 7 and 8 is pivoted respectively at the other end of said rod by pin 9.
  • Gear 10 is a worm wheel properly bearing-supported on case 1, and arm 11 is secured to one end of the rotary shaft of this gear located inside the case.
  • One end of this arm and another end of said link 7 are connected together by pin 12, and gear 10 is meshed with worm 13a of adjustment member 13 provided rotatively on case 1.
  • Head part 13b of this member is supported at a proper place exterior of case 1.
  • Device 14 is a one-directional clutch or drive supported by case 1, and operating piece 14a of this clutch and another end of link 8 are pivoted together by pin 15.
  • Shaft 16 is an output shaft provided so as to rotate only toward one direction by said clutch, and this output shaft is properly bearing supported on case 1, and cloth-pulling roller 17 is secured to the shaft end located exterior of the case.
  • References 18 and 19 denote another output shaft and roller respectively provided in opposed relation to said output shaft 16 and roller 17, and these constitute a so-called cloth-pulling mechanism i.e., when these rollers are rotated in reverse directions by driving gear 20 fitted onto said output shaft 16 and driven gear 21 provided on another output shaft 18 to be meshed with said driving gear 20, cloth to be inserted between said rollers 17, 19 is transferred forcedly toward one side.
  • gear 10 is turned in the direction of arrow (B) by turning adjustment member 13 as shown in FIG. 3, and pin 12 is turned in the direction of arrow (B') by its arm 11.
  • input shaft 2 is rotated similarly to the case mentioned above, operating piece 14a of clutch is once turned to the position shown with chain line, then output shaft 16 is rotated by ⁇ ' angle in the direction of arrow (A').
  • the rotary speed regulating or adjusting member of said output shaft is provided rotatively on the main body case etc., and the adjusting member is meshed with a worm wheel provided also rotatively, and the rotary shaft of said worm wheel and one end of said eccentric rod, and this one end of this eccentric rod and the operating piece of said one-directional clutch, are connected turnably respectively through an appropriate linkage.
